Hi java gurus:
I use servlet as a controller to show pages. If user click "Back" button several times, and execute an operation in the page, at that time the attributes in the session is for the page before clicking "Back". So the operation run with the wrong data. How can I deal with this condition? Can I detect user's click on "Back"?

Thanks for any suggestion.
